After submiiting my application for ITIN to IRS, usually after how many days can I receive notice from them?

I am a non-us citizen. I'm required for an ITIN number for a certain transaction. Now, after submitting my documents to IRS , usually how long does it take before I can receive notice of acceptance or rejection from IRS.It's been 6 months now, since I submitted my application. Anybody help me please.
